Back when I was into the club scene I was the unofficial cock block. I always went to the same club and most people there knew of me, and honestly I'm pretty good at it if I do say so myself(for whatever reason girls would always come to me for help).

Most of the time when you are being "cock blocked" it's because the girl you are chasing actually doesn't want you but she's afraid to piss you off. It's a part of the girl code to be a "cock block" but it's nice to see wholesome men take part in it as well! Always help each other out whenever someone comes up to you obviously uncomfortable. Be their best friend for the next 5 minutes or the next hour, however long it takes for them to feel comfortable again.
